AMENDMENTS TO THE SPECIFICATION

Please amend the specification as follows:

Please replace the paragraph beginning on page 3, lines 28-29, with the
following amended paragraph:

Figure 3 is a sectional view along 2 - 2 of another an alternative
embodiment of the absorbent core 10 of the disposable absorbent article of Figure 1 .

Please replace the paragraph beginning on page 16, lines 19-27, with the
following amended paragraph:

In one preferred embodiment of the present invention the nanoparticles comprise a
synthetic hectorite which can be a lithium magnesium silicate. One such suitable lithium
magnesium silicate is LAPONTrE[[®]], which has the formula:

[MgwLi x Si 8 02oOH 4 . y F y ] >
wherein w - 3 to 6, x ■ 0 to 3, y = 0 to 4, z = 12 - 2w - x, and the overall negative lattice
charge is balanced by counter-ions; and wherein the counter-ions are selected from the
group consisting of selected Na + , K + , NH^, Cs + , Lf , Mg~ Ca~ Ba~ N(CH 3 )4* and
mixtures thereof. (If the LAPONITE[[®]] is '"modified" with a cationic organic
compound, then the "counter-ion" could be viewed as being any cationic organic group

(R))

Please replace the paragraph beginning on page 16, lines 28-30, with the
following amended paragraph:

Other suitable synthetic hectorites include, but are not limited to isomorphous
substitutions of LAPONITE[[®J], such as, LAPONITE Bff™]], LAPON1TE S[[™]] 9
LAPONITE XLS[[™]1, LAPONITE RD[[™]], LAPONITE XLG([™)], and LAPONITE
RDS[[™]J.

Please replace the paragraph beginning on page 20, line 19 - page 21, line 2, with
the following amended paragraph:

Please replace the paragraph beginning on page 21, line 29 - page 22, line 2, with
the following amended paragraph:

Liquid Strike-Through Test - The liquid strike-through time is measured using Lister-type
strike-through equipment, manufactured by Lenzing AG, Austria. Test procedure is
based on standardized EDANA (European Disposables And Nonwovens Association)
method 1 50.3-96, with the test sample placed on an absorbent pad comprised of ten plies
of filter paper (Ahlotrom AHLSTROM Grade 632 obtained from Empirical
Manufacturing Co., Inc., or equivalent). In a typical experiment, three consecutive 5ml
gushes of test liquid (0.9% saline solution) are applied to a nonwoven sample at one
minute intervals and the respective strike-through times are recorded without changing
the absorbent pad.
